Description:To draw a comparison by BLAST between all sequences of prokaryotes, fungi, plants and animals

Abstract:The objective of this project, to run an application on the Grid infrastructure provided by the e-Science network, is to be able to launch BLAST processes in that infrastructure. More precisely, it is to draw a comparison by BLAST between all sequences of prokaryotes, fungi, plants and animals. The results are then analyzed using scripts to estimate the degree of horizontal transfer of genes between prokaryotes and plants. <BR/>To do so, those proteins that are found in prokaryotes and plants but not in animals will be identified, using different similarity thresholds to consider to what extent the similarity between two proteins implies a common origin or not.
